摘要：
A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The processing circuitry is configured to execute the operational instructions to perform various operations and functions. The computing device detects a potentially adverse storage issue with a memory device of a storage unit (SU) of set(s) of storage unit(s) (SU(s)). The computing device also determines whether to transfer at least one EDSs (associated with the memory device) to another memory device for temporary storage therein. Based on a determination not to transfer, the computing device identifies at least one alternate storage location and facilitates transfer of the at least one EDSs for temporary storage therein. When the potentially adverse storage issue has subsided, the computing device facilitates transfer of the at least one EDSs back.
